The Memory and Navigation Lab

Columbia University, Department of Bioengineering


The goal of our work is to characterize the neural signals that represent individual memories. To do this, we study brain recordings from epilepsy patients with implanted electrodes and examine how the recorded signals correspond to behavior in cognitive tasks. Our current work focuses on two areas: spatial and recognition memory. Using this approach, we have identified neural signals that represent specific memory information, including the individual locations in spatial memory and representations of individual verbal items in working memory.
